T 0 all whom it may concern:

Be it known that I, ARTHUR O. AUSTIN, a citizen of the United States, residing at Barberton, in the county of Summit and State of Ohio, have invented new and useful Im rovements in Suspension-Clamps, of.

wire is under tension without dismountingthe clamp.

- The invention contemplates providing a device of the class named comprising a body portion having a grooved flange extending laterally with respect thereto to receive and support the wire or cable, and a movable clamping element cooperating with said body portion for firmly grasping the cable or wire and so arranged as to be. employed without removing any portion of the clamp.

A further object of the invention is to form a portion of the body of the device in such a manner as to be capable of receiving a coupling member for connecting the clamp to an insulatorso as to permit a reasonable amount of movement of the clamp, but so .limiting the movement thereof as to prevent the clamp from striking the insulator, thus eliminating all danger of damage to the latter should the cable or wire break on one side of the clamp, and the clamp itself may be so proportioned that when swung in any direction it will not come in contact with the insulator from which it'is suspended.

A further object of the invention is to construct the movable clamping member with a seat to accommodate or receive aport-ion of the cable or-wire and cooperate with the grooved flange of the body portion to obtain afirm grasp upon the wire or cable.

With theforegoing and other objects in view, the invention consists in the novel construction, combination and arrangement of parts constitutinlg the invention to be here inatter specifica described and illustrated in the accompanying drawings-which form a. part hereof wherein is shown the preferred Specification of flattens Patent.

embodiment of the invention, but it is to be understood that changes, variations and modifications can be reso ted to which come within the scope or" the ciaims hereunto an pended. so

In the drawings in which similar reien ence numerals indicate like parts in the diiiferent figures: Figure 1 is a View in side elevation of a clamp embodying this invention, snowing the same suitably supported by a plurality of insulators. Fig. 2 is a per spective view of the clamp shown in Fig. 1. Figs. 3, 4: and 5 are top, side and end elevations, respectively, of the movable clamping member. Fig. 6 is a sectional View of the clamp on line X of Fig. l; and, Fig. 7 is a section of Fig; 6 on line Y.

My improved clamp embodies a body portion 1, preferably having a greater width than thiclmess and provided at its top with head 2 having therein a recess 3 provided with a contracted, inverted T-shaped mouth 4 and with a contracted opening narroi than the body of said recess extending wardly through the to of said head. T

1S recess is further pre erably formed with curvilinear sides and is adapted to receive the headed end of a pin 6 depending from an insulator unit 7. The head is seated the recess by being passed laterally throng the T-shaped mouth When the head of the pin 6 is seated in the recess, the shank the pin will extend upwardly through the upwardly-extending contracted opening in the head '2. The size of the head of the 6 is such as to permit a limited movement the two members with respect to each other, and when the pin is raised upwardiy wit the recess, the head portion thereoi l within the contracted portion 01. the i 3, The head is further provided wi n transverselyextending opening 5 communi eating with the recess through which a loclo ing key may be inserted for preventing a scentfof the head of the pin and the conse quent withdrawal of the latter.

Each of the insulator units is prefers provided with a cap 8 having the u; r formed in the same manner as tl of the clamp, and as it is customary plurality of these insula s they will ".16 manner s the clamp is connected ti lowermos these units. it wiil be obvious of c that any number of insulator units ed in said groove with the of said groove and a clamping member comprisingabodyportion with oppositely-turned ends, said body portion adapted to engage the upper portion of a cable or wire mountositely-turned ends thereof disposed respectively over said a 'erture and said recess and means for c amping said body portion onto said wire or cable.

4;. A suspension clamp comprising a headprovided with means for connecting the same to a supporting. medium, said head provided with a recess having a T-shaped opening communicating therewith to receive a headed coupling member for supporting said device, the lower part of said'body portion provided with a laterally-extending flange having an upturned marginal edge forming 'a groove to receive a cable or wire, said body portion further provided with an 11 wardly-extending aperture on one side "Q said groove, said upwardly-extending marginal edge provided with a pair of spaced lugs to form a recess between them extending to the opposite side of said groove and a clamping member comprising a body portion with oppositely-turned ends, said body portion adapted to engage the upper portion of a cable or wire mounted in said groove with the oppositely-turned ends thereof disposed respectively over-saidaperture and said recess and means for clamping said body portion onto said wire or cable.

5. A suspension clamp comprising a body portion having a head provided with means for connecting the same to a supportin coupling member, the lower part of sai body portion provided with a laterally-projecting grooved flange, the outer portion of which is upturned to constitute a marginal edge, said marginal edge provided with spaced lugs forming a recess therebetween extending to the grooved portion of said flange, said flange further provided on the opposite side 0 'the groove with an up- .said flange, said flange wardlyextending aperture, a clamping member comprisin a body portion having the under face thereof downwardly-com vexed and shaped to fit a wire or cable po sitioned in said groove and with its ends turned in opposite directions to register with said aperture and said recess and means extending through said aperture and recess'for clamping said body portion onto said cable or Wire.

(3. A suspension clamp comprising a body l portion having a head provided with means forconnecting the same to a supporting coupling member, the lower "part of said body portion provided with a laterally-projecting grooved flange, the floor of said flange formed upon curvilinear lines with the central portion thereof concave and with the adjacent portion convex and with the ends thereof downwardly-turned, the outer portion of said flange .upturned to constitute a marginal edge, said marginal edge provided with spaced lugs forming a recess between them extending to the groove in further provided on the opposite side of said groove with an upwardly-extending aperture, a clamping member comprising a body portion having the under face thereof downwardly convexed and shaped to fit a wire or cable positioned in said groove and positioned with its ends turned in opposite directions to register with said aperture and recess and with its medial convex portion immediately above the concave portion of the floor of said groove and means extending through,

said aperture and recess for clamping said body portion onto said cable or wire,

In testimony whereof I have hereunto set my hand in presence of two subscribing witv HBSSQS.
